Subject: | [lwip-users] Max throughput and LWIP |
Date: | Fri, 1 Feb 2008 16:08:09 -0800 |
I know this is a common topic on the mailing list, but I
wanted to hear about people’s results trying to maximize throughput with lwIP. I am current running lwIP 1.2 on an Atmel AVR32 UC3 at 66MHz.
Using the sequential API with the best lwiopt.h tweaks I can come up with, I am
geting about 350kbps (2.8Mbps). I am not sure how the processor would fair
running NO_SYS using the raw api, but at the moment that is not really an
option. Would that be considered good throughput or is there any simple
tweaks to reach anything closer to wire-speed (10Mbps or even better 100Mbps)? I have read in the mailing list where people were getting approximately
8 – 12Mbps. I am unsure if that was with the standalone raw api, faster
processors, or my settings are just poor. Any suggestions would be appreciated. Best, Josh Rothstein Embedded Systems Engineer DCX-CHOL Enterprises, Inc. 310.516.1692x134 |
